Description

Technical Field

[0001] This utility model relates to a sanitary ware accessory device, and more specifically to an intelligent foaming device for squat toilets. Background Technology

[0002] With the continuous development and progress of science and technology, people have increasingly higher requirements for quality of life and hygiene. Squat toilets, as a primary piece of equipment in restrooms, play an important role in hygiene and convenience. However, squat toilets still have some shortcomings in certain aspects, such as issues with waste disposal, odor prevention, cleaning, and disinfection, especially the unpleasant odor that can permeate the entire room when one person uses the toilet.

[0003] In recent years, some external foaming devices have appeared on the market, which use foam to block the emission of odors and the splashing of dirty water. They are very effective and also play a certain role in cleaning and sterilization.

[0004] However, these external bubble devices require external use, which takes up space and affects aesthetics. Moreover, the bubble devices on the market use electric foam pumps to generate foam, which produces a small amount of foam over a long period of time and cannot seal the excrement in time. The odor of the excrement quickly spreads into the bathroom, causing the whole house to smell bad. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide an intelligent foaming device for squat toilets. The internal components are installed inside the water tank, and the external components are installed on the drain pipe. This invention is compact, easy to install, and solves problems related to odor prevention, splash prevention, non-sticking, cleaning, sterilization, and flushing in toilets. It uses a high-volume fan to generate foam, which can quickly cover the toilet bowl in seconds.

[0006] When the sensor module detects someone approaching, it controls the water pump and fan to start, generating a large number of bubbles. Excrement falls into the bubbles, preventing odor from spreading into the air, thus achieving physical deodorization and maximizing civilized toilet use.

[0007] To achieve the above objectives, according to one aspect of the present invention, an intelligent foaming device for squat toilets is provided, comprising an internal component and an external component.

[0008] Furthermore, the built-in components include a housing, battery, control sensor module, water pump, and hooks. The external components include ventilation components, fan components, spray components, foaming components, and fixing devices.

[0009] It should be noted that the internal components, including the battery, control sensor module, and water pump, are fixed to the outer casing using clips or screws. The outer casing consists of a box and a cover, which are connected to the box using clips or screws.

[0010] Furthermore, the ventilation components, fan components, spray components, and foam outlet components are connected by threads, clips, or bolts.

[0011] Furthermore, the outer casing is provided with a slot, one end of the water pump has an outlet pipe and the other end has an inlet pipe, with the outlet pipe being secured in the slot.

[0012] In a further preferred embodiment, the inlet pipe is provided with a concentrate inlet pipe and a water inlet pipe via a tee; the inner diameter ratio of the concentrate inlet pipe to the water inlet pipe is 1:5 to 1:2.

[0013] Furthermore, check valves are installed on the liquid outlet pipe, the concentrate inlet pipe, and the water inlet pipe to prevent liquid backflow, and a vent valve is installed on the liquid inlet pipe to prevent siphoning.

[0014] Furthermore, the ventilated component is equipped with air inlets, which are angled downwards and outwards to prevent external water from entering the blower component. The blower component has external holes, and the blower is secured internally with screws or clips; the blower speed is 5m / s-20m / s. The spray component is curved at an angle greater than 90° to facilitate better bubble formation and prevent bubble accumulation in the bubble outlet component.

[0015] Furthermore, the spray assembly internally houses the nozzle and a foaming net via screws or clips; a sleeve is installed on the foaming component, which moves up and down within the foaming component. The inlet end of the nozzle is connected to one end of the outlet pipe. The foaming net is located below the nozzle, and the holes in the foaming net are open.

[0016] It should be noted that the sleeve can be adjusted by simply slipping it onto the bubbling component and moving it up and down, or by using a threaded adjustment structure; or by using a sliding structure with a limiting groove for up and down adjustment; or by using tape, glue, etc. to fix the sleeve for adjustment, and there is no limitation on this adjustment method.

[0017] A further preferred embodiment is a cable tie, Velcro, or buckle. The fixing device passes through a hole on the outside of the blower component and is fixed to the drain pipe of the squat toilet tank at the junction of the drain pipe and the ground. The bubble outlet on the bubble outlet component faces into the squat toilet.

[0018] Furthermore, the built-in components are attached to the inside of the squat toilet's flush tank via hooks, with the installation position above the normal water level line. A small hole is located on the side of the flush tank, through which the discharge pipe exits. The battery, control sensor module, water pump, and fan are electrically connected to the control sensor module. The sensor module can be a radar sensor, a Wi-Fi receiver, a 2.4G receiver, or a 5G receiver. The radar sensor module can directly detect and transmit information to the control sensor module, which then operates according to a pre-set program. The Wi-Fi receiver, Bluetooth receiver, 2.4G receiver, or 5G receiver module works in conjunction with a remote control.

[0019] It should be noted that the batteries can be individual lithium batteries or battery packs. The batteries can be charged inside the built-in bubble machine via a circuit board. Alternatively, the batteries can be removed and charged with an external charger. The interface between the battery and the circuit board can be soldered or connected via a flexible joint for easy battery removal.

[0020] Furthermore, a smart foaming device for squat toilets includes an automatic mode operating scenario:

[0021] ① Install the built-in components inside the squat toilet tank and fix them in place. The installation position should be higher than the normal water level line of the tank. Insert the concentrate inlet pipe into the concentrate container and place the concentrate container inside the squat toilet tank.

[0022] ② Turn on the switch, the radar sensing module starts working, and the control sensing module starts working; when a person is detected, the fan and water pump start working for 1-20 seconds and then stop working;

[0023] ③ If the bubbles are not producing properly, check if the battery is low on power and if there is still undiluted solution in the container.

[0024] Compared with existing technologies, this invention has the following advantages: The product is simple to use, with a built-in concealed design, installed inside the water tank and at the drain pipe, saving space. This product is compact and easy to install, solving problems related to toilet odor prevention, splash prevention, non-sticking, cleaning, sterilization, and automatic flushing. It uses a high-volume fan to generate bubbles, which can quickly cover the toilet bowl in seconds. Attached Figure Description

[0031] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0032] See Figures 1 to 5 The illustrated device is an intelligent foaming unit for squat toilets. This product is simple to use, featuring a built-in, concealed design that installs within the water tank and at the drain pipe, saving space. It employs a liquid-machine separation method; when the undiluted undiluted condensate is depleted, the container can be removed for refilling or replacement. Compact and easy to install, this product solves problems related to toilet odor prevention, splash prevention, non-sticking, cleaning, sterilization, and automatic flushing. It uses a high-volume fan to generate foam, quickly covering the toilet bowl in seconds.

[0033] Specifically, the product includes an internal component 1 and an external component 2. The internal component 1 includes a housing 11, a battery 12, a control sensor module 13, a water pump 14, and a hook 15. The external component 2 includes a ventilating component 21, a fan component 22, a spraying component 23, a foaming component 24, and a fixing device 25.

[0034] Reference Figure 3 and Figure 4The outer casing 11 has a slot 111. One end of the water pump 14 has an outlet pipe 32, and the other end has an inlet pipe 31. The outlet pipe 32 is secured in the slot 111. The pipes are flexible, with moderate hardness; too stiff and they are unsuitable for shaping, too soft and they are easily folded, affecting liquid inlet and outlet. The inlet pipe 31 is connected to a concentrate inlet pipe 311 and a water inlet pipe 312 via a tee. The inner diameter ratio of the concentrate inlet pipe 311 to the water inlet pipe 312 is 1:5 to 1:2. The concentrate concentration is relatively high; by using different pipe diameters to mix with water, the desired foaming effect is achieved, saving concentrate, extending usage time, and eliminating the need for frequent additions or replacements by the user.

[0035] Furthermore, check valves 34 are installed on the liquid outlet pipe 32, the concentrate inlet pipe 311, and the water inlet pipe 312, and an air vent valve 33 is installed on the liquid inlet pipe 31. The check valves prevent liquid backflow, prevent water in the water tank from flowing into the concentrate container, and prevent liquid in the concentrate container from flowing into the water tank. The air vent valve 33 on the liquid inlet pipe 311 prevents siphoning.

[0036] like Figure 2 As shown, the external components 2, from top to bottom, are: a ventilating component 21, a fan component 22, a spray component 23, and a foaming component 24. The fixing device 25 is located on the fan component 22.

[0037] Specifically, the venting component 21 is equipped with an air inlet, which is angled downwards and outwards. This design prevents water from entering the blower component 22 when water is sprayed from the external component 2, allowing it to flow out through the angled vent. The blower component 22 has external holes, and the blower 221 is fixed internally by screws or clips. The spray component 23 is curved at an angle greater than 90° to facilitate better foam distribution and prevent foam accumulation in the foaming component. The nozzle 231 and the foaming net 232 are fixed internally by screws or clips; the foaming net 232 is an open-pore mesh of a certain thickness. The foaming component 24 is equipped with a sleeve that moves up and down. For users whose drain pipes are at different distances from the toilet bowl, the sleeve can be used for adjustment, allowing the foam to flow smoothly into the toilet bowl.

[0038] Specifically, the ventilated component 21, the fan component 22, the spray component 23, and the bubble-generating component 24 are connected by threads, clips, or bolts. The fan speed is 5m / s-20m / s. After multiple experiments, it was found that a wind speed of 5m / s or higher is required to produce satisfactory bubbles. The higher the wind speed, the better the quantity and speed of bubble production. However, as the wind speed increases, the noise also increases. Therefore, the maximum wind speed is controlled below 20m / s to better control noise.

[0039] Furthermore, the inlet end of the nozzle 231 is connected to one end of the outlet pipe 32. The foaming net 232 is located below the nozzle 231. The nozzle 231 sprays the liquid evenly onto the foaming net 232, and then the large volume of air blown by the blower 221 forms bubbles and blows them out.

[0040] Furthermore, the fixing device 25 is one of cable ties, Velcro, or clips, mainly to facilitate fixing the external component 2 to the drain pipe. The fixing device 25 passes through the hole provided on the outside of the blower component 22 and is fixed to the drain pipe of the squat toilet tank at the junction of the drain pipe and the ground. The foam outlet on the foaming component 24 faces into the squat toilet.

[0041] like Figure 1 and Figure 5 As shown, the built-in component 1 is attached to the inside of the squat toilet flush tank via a hook 15. A small hole is opened on the side of the squat toilet flush tank, through which the liquid outlet pipe 32 passes. The water inlet pipe 312 draws water directly from the water tank, and the concentrate inlet pipe 311 is inserted into the original liquid container.

[0042] Furthermore, the battery 12, control sensing module 13, water pump 14, and fan 221 are electrically connected to the control sensing module 13. The control sensing module 13 can be a radar sensor module, a Wi-Fi receiver module, a Bluetooth receiver module, a 2.4G receiver module, or a 5G receiver module. The radar sensor module can directly sense objects and transmit the detected information to the control sensing module, which then operates according to a pre-set program. The Wi-Fi receiver module, Bluetooth receiver module, 2.4G receiver module, or 5G receiver module is used in conjunction with a remote control.

[0043] It should be noted that the batteries can be individual lithium batteries or battery packs. The batteries can be charged inside the built-in bubble machine via a circuit board. Alternatively, the batteries can be removed and charged with an external charger. The interface between the battery and the circuit board can be soldered or connected via a flexible joint for easy battery removal.

[0044] The working principle and beneficial effects of this utility model will be specifically illustrated below through examples. Example 1

Press the automatic button, and the fan and water pump will start working for 1-20 seconds and then stop. Press the manual start button, and the fan and water pump will start working. Press the stop button, and the fan and water pump will stop working.

[0054] ④ If the bubbles are not producing properly, check if the battery is low on power and if there is still undiluted solution in the container.

[0055] It should be noted that, in addition to the foam-generating surfactants, the bubble-producing concentrate can also contain antibacterial agents, pigments, and fragrance components, resulting in better cleaning, sterilization, and deodorization effects. The concentrate in the container can also be configured according to specific customer requirements. In the above embodiment, when the concentrate container is empty, there is no notification to the user; the user needs to manually replenish the concentrate when bubbles are not being produced. However, this built-in component 1 can also be equipped with a liquid sensor or liquid level sensor on the concentrate container. When the liquid level in the concentrate container falls below a set value, the product stops working and prompts the user that the liquid level in the container is low and needs to be replenished.

[0056] The advantages of this invention are: The product is simple to use, with a built-in concealed design that installs inside the water tank, saving space. Installation does not affect the use of the water tank buttons. This compact product is easy to install and solves problems related to toilet odor prevention, splash prevention, non-sticking, cleaning, sterilization, and automatic flushing. It uses a high-volume fan to generate bubbles, quickly covering the toilet bowl in seconds. The product can be configured via a communication module, and future upgrades can unlock more functions.
